5. The Importance of SharePoint Security

6. What is SharePoint? SharePoint is: “A site-provisioning engine” No really, SharePoint is: A website A series of databases An application platform SharePoint touches: Your network Your Active Directory Your LOB Systems SharePoint is a platform with a large attack surface

7. SharePoint is Everywhere Over 20,000 new SharePoint seats have been added every day for 5 years Over 1,500 high profile websites on SharePoint SharePoint is becoming increasingly “business critical” SharePoint is commonly used for Intranets Extranets Internet Sites Application platforms

8. Types of Security Threats Threats we’re going to explore today: Data disclosure / theft Data loss System downtime Types of attacks: Cross-site scripting (XSS) Cross-site request forgery (CSRF) Clickjacking Privilege escalation “Man in the middle” / replay attacks SQL injection If it’s a threat to other websites or databases, it’s a threat to SharePoint

10. Facets of SharePoint Security

11. Example:They keep piling up!

12. Planning for Security

13. Planning for Security Plan personas and define permission matrices Understand content and security contexts Determine authentication, SSO, and federation goals Use the SharePoint 2010 upgrade as an opportunity to apply governance Don’t expect the default settings to protect you

14. Example:How’d you build that?

15. Anonymous Access Carefully decide if SharePoint is the right platform for anonymous access Especially consider implications for public blogs and wikis Always use the site lockdown feature “Get-SPFeatureviewformpageslockdown” Further restrict pages using web.config or UAG Add SharePoint to your website security testing Don’t lock out the /_layouts path altogether

16. Example:I don’t think we’ve met…

17. Authentication and Directory Security Synchronize only the AD users relevant for social features Don’t bring confidential information into user profiles Understand the impacts of third-party federation Track and block rogue SharePoint installations with “Service Connection Points” Develop a password change / managed account strategy

18. Example:Private audience?

19. Content Security Audiences are not security Search content rollups make bypassing audiences simple Item-level permissions / broken permission inheritance should be the exception, not the rule Avoid using policies to override permissions PDFs = Pretty Dangerous Files Consider Information Rights Management and auditing

20. Example:The man in the middle…

21. Network Security Always use SSL for authenticated access Firewall all nonessential public ports Host all servers on the same vLAN Use IPSec for geo-distributed communication Be aware of “loopback check” implications

22. Network Security

23. Example:I’m with him…

24. Application Security Never expose SharePoint’s application tier to the internet Don’t host Central Administration on a web front-end Isolate service accounts and use standard naming conventions Use multiple IIS application pools (but not too many) Never use CNames

25. Example:Thanks for the backup!

26. Database Security Isolate SharePoint databases from other systems Minimize the SQL surface area by disabling unneeded features Consider SQL 2008 “Transparent Data Encryption” Performance impact, backup size impact, and file stream impacts Don’t leave SharePoint backups within the content database or on web-front ends

27. Example:Your health is showing.

28. Connected System Security Remove the X-HealthScore, MicrosoftSharePointTeamServices, and other identifying headers Leverage the Secure Store Service for safely accessing external systems via BCS Avoid reliance on Flash content Consider ForeFront UAG endpoint security Set policies regarding data being stored offline

29. Example:Could you do this for me?

30. Custom Development Security Build security testing into the SDLC for all custom and third-party components Take advantage of CAS policies and the ULS logs Utilize sandbox solutions whenever possible Minimize use of RunWithElevatedPrivilege() With SharePoint 2010, Javascript is now the biggest threat

31. Example:You don’t want this help…

32. Security Maintenance and Monitoring If running WSS/MOSS, patch to October 2010 CU or install MS10-039 Keep SharePoint, Windows, and SQL patched to latest service packs Deploy server-side virus protection Use Systems Center Operations Manager with SP health rules to monitor for performance spikes or errors related to attacks Build security assessments and spot checks into other SharePoint maintenance plans Familiarize self with “Site Permissions > Check Permissions”
